Try to emphasize the ways in which Flotilla is similar to Discord. For instance, you join a server through an invite link, and that servers on flotilla has channels like on discord, and you can even list the features that arent yet there but are planned and simply put a link to the roadmap next to unfinished features with an "In Progress" badge above the title. For instance role based access control with role names and colors, voice channels with push to talk, DMs, custom emojis, and whatever else.
